Seal Marble Tiles Before Grouting
Marble is porous and could easily absorb color from the grout, so it's important to seal the stone before you grout — even if you're using white grout. Just rub the tile's surface with a soft cotton rag that's damp with stone sealer.
Accordingly, do you need to seal polished marble?
If my marble surface is polished to a high finish, does it still need to be sealed? Yes. Marble and natural stone regardless of the finish is still porous and is susceptible to dirt penetrating the surface and staining. The surface still should be sealed with a penetrating sealer.
Also Know, how long after sealing marble can I grout?

Use an impregnating sealer for best results.
- Fill a spray bottle with a commercial stone cleanser or a mild, pH-neutral cleanser.
- Sponge a thick, even layer of marble sealer onto the stones.
- Wipe the excess sealer off the marble with a dry cloth after 15 minutes.
- Apply a second coat of sealer and repeat the process.
